After her brave admission, she went on to post photographs of women she admires in the film industry, alongside empowering quotes from them about women, in support of the United Nation’s Girl Up campaign.

And now Reese and Susan, who were mentioned by Cara in her Instagram reel, have responded with support for Cara, telling her they’ve ‘got her back’.

Actress Reese, who has never worked with Harvey, wrote: ‘Love you, my fellow warrior.’

And Susan replied: ‘I’m a huge fan of your spirit, talent and potential and now your bravery for speaking out. Next time anything bad happens, I got your back.’

A second post contained the quote: ‘The devil whispered in my ear, “you’re not strong enough to withstand the storm”. Today I whispered in the devils ear, “I am the storm”.’

She added: ‘I want women and girls to know that being harassed or abused or raped is NEVER their fault and not talking about it will always cause more damage than speaking the truth.

‘I am relieved to be able to share this. I actually feel better and I’m proud of the women who are brave enough to speak. This isn’t easy but there are strength in our numbers.

Cara Delevinge's full claims against Harvey Weinstein

'When I first started to work as an actress, I was working on a film and I received a call from Harvey Weinstein asking if I had slept with any of the women I was seen out with in the media. I was a very off and uncomfortable call… I answered none of his questions and hurried off the phone but before I hung up, he said to me that if I was gay or decided to be with a woman especially in public that I’d never get the role of a straight woman or make it as an actress in Hollywood.

'A year or two later, I went to a meeting with him in the lobby of a hotel with a director about an upcoming film. The director left the meeting and Harvey asked me to stay and chat with him.

As soon as we were alone he began to brag about all the actresses he had slept with and how he had made their careers and spoke about other inappropriate things of a sexual nature.

'He then invited me to his room. I quickly declined and asked his assistant if my car was outside. She said it wasn't and wouldn't be for a bit and I should go to his room. At that moment I felt very powerless and scared but didn't want to act that way hoping that I was wrong about the situation.

When I arrived I was relieved to find another woman in his room and thought immediately I was safe. He asked us to kiss and she began some sort of advances upon his direction. I swiftly got up and asked him if he knew that I could sing.

And I began to sing... I thought it would make the situation better... more professional... like an audition... I was so nervous. After singing I said again that I had to leave. He walked me to the door and stood in front of it and tried to kiss me on the lips. I stopped him and managed to get out of the room.

'I still got the part for the film and always thought that he gave it to me because of what happened. Since then I felt awful that I did the movie. I felt like I didn't deserve the part. I was so hesitant about speaking out... I didn't want to hurt his family. I felt guilty as if I did something wrong. I was also terrified that this sort of thing had happened to so many women I know but no one had said anything because of fear.'

‘As I said, this is only the beginning. In every industry and especially in Hollywood, men abuse their power using fear and get away with it. This must stop.

‘The more we talk about it, the less power we give them.

‘I urge you all to talk and to the people who defend these men, you are part of the problem.’

Cara has worked with Harvey on two films – Free The Nipple in 2014 and Tulip Fever, which is released this year.

Weinstein faces a number of sexual assault allegations, which emerged this week and details alleged incidents that took place over three decades. Actresses Angelina Jolie, Gwyneth Paltrow, Ashley Judd and Rose McGowan are among the accusers.

An audio recording made by a Filipina-Italian model named Ambra Battilana Gutierrez also features Weinstein pleading with her to enter a bathroom and watch him have a shower.

Weinstein has been fired from his company The Weinstein Company over the allegations and his wife Georgina Chapman has confirmed she has left him. His BAFTA membership was suspended on Wednesday.
